Research Prominence

William Leggett receives prestigious lifetime achievement award

Dr. William Leggett.

William Leggett, professor emeritus in the Department of Biology and Queen's 17th principal, has received the H. Ahlstrom Lifetime Achievement Award from the Early Life History Section of the American Fisheries Society for his contributions to the fields of larval fish ecology.

The American Fisheries Society is the biggest association of professional aquatic ecologists in the world, with over 9,000 members worldwide.

"œIt feels good to be singled out by such large group of people who I respect so highly," says Dr. Leggett. "œI didn'™t expect to receive this award so it'™s a big honour and thrill to get it."

Dr. Leggett'™s research focuses on the dynamics of fish populations and his work as a biologist and a leader in education has been recognized nationally and internationally. A membership in the Order of Canada, a fellowship from the Royal Society of Canada, and the Award of Excellence in Fisheries Education are just some of the awards he has received for outstanding contributions to graduate education and marine science.

The Early Life History Section of the American Fisheries Society recognized Dr. Leggett'™s "œexceptional contributions to the understanding of early life history of fishes that has inspired the careers of a number of fisheries scientists worldwide and has led to major progress in fish ecology and studies of recruitment dynamics."

The award was recently presented in Quebec City at the 38th annual Larval Fish Conference held in conjunction with the 144th annual meeting of the American Fisheries Society.


Looking for a definitive cure for HIV

Infectious diseases clinician and researcher Santiago Perez is advancing work on HIV immunology and the ongoing search for a cure.

Dr. Santiago Perez is an infectious disease clinician and researcher working on HIV cure research.

A lot has happened since the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) were first described in the early 1980s. Sexual health education campaigns have helped to curb transmission in most developed countries. Thanks to effective drugs, being infected no longer equals a death sentence. Yet, over 60,000 people in Canada and 37.7 million people worldwide still live with HIV and depend on medications daily, and for the rest of their lives. That's the only way to keep their viral loads low enough to avoid developing AIDS symptoms or transmitting the virus to others.

This is why scientists are still looking for a definitive cure: a short-term treatment capable of eliminating the virus for good. Taking part in this global effort is Santiago Perez, an infectious disease clinician and researcher in the Faculty of Health Sciences.

“I had a personal interest in HIV very early on my career,” Dr. Perez says. They were a medical student in the 1990s, when AIDS mortality rates were peaking. The scientific community was just beginning to unravel the complexity of the disease. “I felt compelled to do something to help.” Before joining Queen’s in 2019, they had been working in HIV immunology research in Mexico and France.

Dr. Perez is particularly interested in acute HIV infection and the human immune response. One of the biggest questions still lacking a satisfactory answer is how HIV manages to “hide” in the human cells. The virus gets to the point of being undetectable in patients undergoing treatment. If therapy is interrupted, it multiplies again.

HIV is a retrovirus, meaning it can insert its own genes in the DNA of infected cells. This is why immunization (via vaccines) and cure are so hard to accomplish. The most effective treatments so far are antiretroviral drugs, which suppress virus replication.

Scientists are now looking at CAR T-cell therapy, a particular form of immune therapy traditionally used to treat leukemia and other forms of cancer, to defeat HIV. “The idea is to take lymphocytes from the patient and reprogram them – using genetic engineering – to fight a particular molecule,” explains Dr. Perez. “The reprogrammed cells are then inserted back in the patient and start fighting the cancerous cells.” To be able to do the same with HIV, scientists are looking for biomarkers that can be used as targets for the CAR-T cells.

While recognizing this is a very bold goal, Dr. Perez is excited to advance this research because of the potential benefits for the patients.

“Even though people can now live with HIV, they still face the stigma. They still have to go to the doctor, take pills, and run blood work. When I talk to people living with HIV about this, they all say they wish there was a way to get rid of the virus. That’s why I’m motivated to find a cure for HIV,” Dr. Perez says.


Disease within a context

HIV infection has a close relation to human behaviour and social factors. In the rise of the AIDS pandemic, the disease was described as particularly affecting homosexual men. But this does not reflect the full picture.

Most people living with HIV in the Americas and Europe are male. But in Africa – the continent with the highest HIV infection prevalence – women are more affected than men. In South Africa, the major risk factors are being female and under the age of 17, often a result of sexual abuse and sex trafficking. “Even though women represent more than half of people living with HIV worldwide, they have been excluded from research because of the assumption that the virus affects more men than women,” highlights Dr. Perez.

Social determinants of health play a crucial role in how HIV spreads among populations. In their clinical practice in Kingston, Dr. Perez notes that many patients use intravenous drugs. These patients were possibly contaminated by infected syringes. Many are also in and out of prison. In Ontario, only patients over 65 have access to free antiretroviral treatment for HIV. These layers of complex social dynamics and access – that vary within provinces and cities across Canada – pose challenges for HIV prevention, treatment, and research.

Around the world, stigma is still one of the biggest challenges in combating HIV. “It prevents people from getting tested and from engaging in care,” says Dr. Perez.

Another huge challenge is how to provide access to treatment in low-income countries. “New therapeutics or curative treatments need to be available for global distribution, not only for rich and developed countries. Research must take that into account”, states Dr. Perez.

Dr. Capicciotti is a Queen’s National Scholar whose interdisciplinary research in glycobiology and carbohydrate chemistry has been recognized as innovative on an international scale. Drawing from chemistry, biochemistry, and cell biology, she has developed streamlined methods to synthesize complex carbohydrates, and novel biochemical tools to study their interactions. Dr. Capicciotti leverages this interdisciplinary work to understand the biological functions of these crucial biomolecules. Her research is providing innovative insights into the role that the thick ‘sugar coating’ on cells plays in human health and disease, including cell signalling, virus infections, and cancer immune evasion.

The Prizes for Excellence in Research will be presented during convocation. To learn more about the awards, or past recipients, visit the Vice Principal (Research) Portfolio website.

Launch of Research Discovery Network

The Vice-Principal Research Portfolio has spearheaded a new initiative to support the Queen’s research community and enable interdisciplinary collaborations. The Research Discovery Network (RDN) is a digital platform designed to spark new engagement with groups in academia, industry, media, and communities from across campus to around the world.

The RDN builds off the success of Queen’s Translational Institute of Medicine (TIME), which has used the system since 2017. The platform has enabled TIME to showcase the breadth of their translational research, identify opportunities for members to collaborate, and maintain a directory for the state-of-the art technologies available for use at Queen’s. The university is now extending that network to researchers looking for profile and engagement for their own research, that of their group or lab, or sharing their research resources.

The two main features of the RDN include hosting a public profile and CV management. The profile tool helps researchers showcase their research interests, active projects, publications, and media engagements for optimized discovery on the network. Researchers are also able to leverage the network’s robust topic tagging system to find other researchers at the university to build collaborations and connections. The RDN also supports CV management through direct integration with the Canada Common CV (CCV) system. Researchers can simultaneously update their CCV and their public research profile while using a more intuitive and streamlined interface.

Profile-building is currently underway with information and resources, such as drop-in and training sessions and direct support, available on the Vice-Principal Research Portfolio website. A how-to webinar is also scheduled for June 22 with registration available as part of the Resources for Research at Queen’s (R4R@Q) series. If members of the research community have any questions or are looking for further information, a direct contact form is also available. 

$3.6 million boost for social sciences and humanities research

Federal funding announced today included support for 21 Queen’s researchers.

Today the Government of Canada and the Social Sciences and Humanities Research Council (SSHRC) announced the results of grants under the umbrella of the Insight Program, which aims to advance our understanding of how individuals and societies think, live, and interact with each other and with the world around them. The program has a special focus on research that addresses complex societal challenges and opportunities.

“Now, more than ever, social sciences and humanities research plays an integral role as we navigate through the post-COVID-19 reality and continue to build a healthier, stronger and more prosperous Canada,” said the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry. “These grants enable scholars to address complex issues about communities and societies, and to further our collective understanding so we can build a better future for all Canadians.”

Twenty one Queen’s researchers received funds totaling $ 3.6 million to advance their research projects.

“These important SSHRC programs fund projects at all stages of the research continuum – from early investigation to the dissemination of results,” says Nancy Ross, Vice-Principal (Research). “The Queen’s projects all approach societal challenges in creative and innovative ways and, ultimately, support us in better understanding the world around us.”

The Insight Grants provide long term support (over two to five years) to research initiatives led by emerging and established scholars. Applicants are encouraged to consider addressing one or more of the 16 future global challenges identified by the SSHRC’s Imagining Canada’s Future initiative.

The Partnership Development Grants fund new or existing teams doing research or activities – including knowledge mobilization – in the social sciences and humanities, or designing and testing new models for research and related activities that can be amplified to a regional, national, or international level.

Finally, the Aid to Scholarly Journals aims to increase the dissemination of research results and encourage open-access publishing by supporting journals and their distribution on Canadian non-profit platforms.

COVID-19, the second pandemic of the current century, is still an ongoing global health emergency. Its complications and mortality are associated with pneumonia and alterations in the pulmonary vasculature. Acquiring 3D images of vascular trees in animal models provide a useful tool to evaluate the effects of COVID-19 in humans. In our research aimed at finding new drugs for COVID-19 under the supervision of Dr. Stephen Archer, vascular trees of a mouse were pressure perfused to maximal dilation with a radio-opaque material (barium). The heart and lungs were fixed and scanned using VECTor4CT scanner. VECTor4CT is the first tri-modality imaging system equipped with an ultra-high-resolution micro-computed tomography (µCT) scanner at Queen’s University.

Location: Gjoa Haven, Nunavut

The Inuit practice an ongoing relationship with the land through camping, hunting, and fishing. As part of the BearWatch project, I explore how such knowledge, accumulated over many generations, and Inuit values can be ethically engaged in a community-based polar bear monitoring program. This picture is taken on one of our trips out on the land around Gjoa Haven during spring 2022. It captures George Konana collecting ice from the lake for tea. He traces ice with the right quality to give his tea a nice ‘reddish, brown’ color. At this exact moment, he cracks out a huge piece, enough for a month of tea.

Gastropod Mummy

Submitted byRuqaiya Yousif
PhD Student, Geological Sciences and Geological Engineering
Location: Qatar

This is a picture of a gastropod mummy laying down her egg cases. My research assesses the stable isotope (C and O), clumped isotope (∆47), and trace element compositions of living and quaternary shells from the Arabian/Persian Gulf. The aim is to link these analyses with modern oceanographic data to develop a robust proxy for understanding oceanographic change in the rock record. In other words, I am trying to link the shell chemistry with its surrounding environment and then use this link to assess oceanographic changes over the past 125,000 years. At the time of this picture, we were growing gastropods under laboratory conditions and performing invitro fertilization of oysters.

Location: Coral Harbour, Nunavut

This photo demonstrates the collection of snow from inside a maternal polar bear den to collect environmental DNA. When the mother digs out the den, skin cells from her paws are abraded and stuck to the snow. Some preliminary research shows that we may be able to identify individual bears by analyzing these snow samples, information which can inform polar bear population management. My research is a pilot of ground-based non-invasive polar bear monitoring techniques, with a focus on Inuit inclusivity. Inuit Elders and polar bear hunters are key knowledge holders and collaborators throughout this research.

Crystalline Acid

Submitted byDan Reddy
PhD Student, Chemistry
Location: Chernoff Hall, Queen's University

This photo taken with scanning electron microscopy depicts an extremely small yet precise volume (i.e., nanolitre-sized) of crystallized decanoic acid. We are using these spots of crystalline acid to extract and preconcentrate, or soak-up, chemicals of concern like opioids from wastewater samples. This preconcentration step improves our ability to monitor these chemicals. By doing so, we can improve how we detect these harmful compounds and protect local watersheds.

What we need to build a more inclusive future

Human resources management expert provides insights on gaps and best practices in addressing equity, diversity, and inclusion in the workforce.

As Canadians celebrate both Pride Month and Indigenous History Month, June seems like the perfect time to reflect on the different aspects of equity, diversity, and inclusion (EDI) – how we’ve worked to implement EDI in our lives and practices and the work we still need to do. One area that has seen attention over the past decade is how EDI practices can be beneficial for institutions and businesses.

Eddy Ng
Eddy Ng

Eddy Ng, the Smith Professor of Equity & Inclusion in Business and an expert in human resources management, focuses his research on how we can promote EDI in workplaces across Canada. He recently spoke to the Gazette about how the COVID-19 pandemic has deepened existing gaps and what current research says about hiring and management practices to promote EDI.

How did COVID-19 increase gender related inequalities?

First, women are disproportionately affected by business closures (e.g., retail, hospitality, service-oriented work) and hence they suffer in employment and income in relation to men. The aggregate number of hours worked by women decreased significantly, and the number of women owned businesses declined as a result of the pandemic. Thus, the gap employment and income gaps between men and women widened.

Also, pre-existing conflicts between work and family responsibilities magnified during COVID-19. Women shoulder a disproportionately larger share of household chores and caregiving. School and daycare closures have forced a third of working women to consider quitting their jobs. A noteworthy point of observation, women are less represented in senior management and leadership roles – which tend to be more pandemic-proof. 

We hear about post-pandemic economic recovery and a shortage of skilled workers. However, Indigenous and Black workers still struggle finding jobs that are consistent with their professional competencies. Why?

The post-pandemic recovery has seen a boom in the tech sector and sectors that are adaptable, but Black and Indigenous workers still are underrepresented in tech and other booming sectors such as banking and financial services, STEM professions, and information and communications technology. Historically, Black and Indigenous workers have lower levels of educational attainment and possess job skills that are prone to automation. Simply put, Black and Indigenous workers have not been set up for success in new economy jobs and in remote or “pandemic proof” careers. To address employment gaps, we need to have policies aimed at preparing Black and Indigenous populations for the new economy, and industry commitment as partners in the training and employment of severely underrepresented racialized workers.

Individuals are differently impacted based on a combination of factors (race, citizenship, gender, class, sexual orientation etc.). Do existing EDI practices address intersectionality?

Intersectional marginalized identities tend to be invisible; the Black lesbian small business owner is grouped with other Black small business owners. EDI policy surveys tend to address identities that are measurable or quantifiable, thus individuals with intersectional identities don’t receive the same attention. To address this, policy makers need to decompose aggregate data or collect better data. The challenge, as reported here, is getting individuals to respond to policy questions. Alternatively, equity policies should be as broad as possible to ensure that individuals with multiple struggles are able to receive more comprehensive support.

Hiring practices that aim to foster diversity and inclusion are frequently criticized based on the hypothesis that they might favour minorities and fail to find the best candidates for a position. Is that a fallacy? Why?

Hiring for diversity and hiring for excellence are not in conflict with each other. Hiring the "best" candidate implies there is a singular view of what is the best, established by the dominant group, so we are reproducing the dominant group perspective. This is why it is important to have targeted hirings so that we are not crowded out by dominant group views. Meritocracy and picking "the best" favour the dominant group that establish the rules. 

What strategies are successful in creating more diverse and inclusive hiring processes and promoting EDI in workplaces?

In comparing firms that are covered under the Employment Equity Act with those that are not, research shows that firms having to comply with public policies do better in hiring for diversity. Public policies create visible accountability across firms. Research also shows that leaders who create accountabilities for diversity goals, lead more diverse organizations. Implicit bias training, however, does not work well for several reasons. First, bias training tends to emphasize the negative (i.e., remedial training), generating skepticism and resistance among participants. Thus, bias training does not change attitudes or behaviours. Second, hiring managers don’t like to be told whom to hire. People tend to rebel against rules when discretion is taken away from them. Third, bias training, when improperly conducted, can reinforce stereotypes and undermine its very own purpose in removing biases.

We already have the knowledge and skills on how to become more diverse and inclusive. What is lacking are motives. Accountability and incentives provide that motive. Once we have the critical numbers in diversity, demographic faultline weakens and organizational climate shifts to one that is more accepting of differences. 

International effort to reduce concrete’s carbon footprint

A team of civil engineering researchers and industry and municipal partners are working to make one of the highest-carbon dioxide producing industries much cleaner.

Student working at Queen's civil engineering lab
Making the concrete industry more sustainable and environmental-friendly is the main goal of the research partnership.

How environmentally friendly is concrete? Less so than you might think. Reinforced concrete infrastructure accounts for almost 10 per cent of global carbon dioxide emissions – far ahead of the two per cent of carbon dioxide produced by the airline industry.

Working to change that are two Queen’s civil engineering experts Neil Hoult and Josh Woods, together with their academic collaborators at the University of Toronto and the University of Cambridge and a number of industry partners who are invested in making their technology and processes more sustainable.

“If we can reduce the carbon produced in concrete manufacturing by even a fraction, it’s going to have a significant positive benefit,” says Neil Hoult, a professor in the Department of Civil Engineering. “Increased urbanization means that the demand for concrete is going up. Our research aims to cut the carbon dioxide emissions generated by concrete production in half – the equivalent of eliminating the airline industry, twice over.”

The research program is supported by industry leaders like Arup, Aecon, KPMB Architects, and Lafarge, along with the City of Kingston and the Cement Association of Canada, with funding sources including Natural Sciences and Engineering Research Council of Canada (NSERC) and Mitacs.

To achieve the goals set by Queen’s and its partners, several approaches will be explored to reduce carbon utilization. The first one is shape optimization, meaning studying how to better design structures to use less concrete – which reduces both material consumption and structure weight.

Neil Hoult and students
Neil Hoult and students work to reduce carbon utilization in concrete structures.

The second is what’s known as functionally graded concrete.

“We put concrete with higher strength where we need the strength, then we use lower strength concrete (which also means lower cement concrete) everywhere else,” Dr. Hoult explains. “We will be working on software packages that allow for these new techniques to be used in the design, optimizing structures for performance and low environmental impact.”

The bulk of the initial research and testing will be completed in the Queen’s civil engineering labs. Moving from the lab to practical applications, however, will take the project into the real world in Kingston, with the support of city and industry partners. The project includes the design of a demonstration structure at the Kingston Fire and Rescue Training Centre.

“The structure will be actively used by Kingston’s Fire Services as a classroom and as a living lab so that Queen’s and St. Lawrence College students can come and learn about low-carbon buildings. We’re aiming for a net-zero building philosophy,” Dr. Hoult highlights.

Speros Kanellos, Director, Facilities Management, and Construction at the City of Kingston, says the city has been working with post-secondary educational partners on ‘learning hubs’ to investigate new approaches and technologies to aggressively decarbonize infrastructure.

“We are working with the low-carbon concrete research team to develop a real-world application for demonstration purposes and ongoing research,” he says. “It’s really exciting to participate as a partner in the kind of initiative that embodies the City’s and university’s leadership on climate action.”

Partnership for health innovation

An evolution of the Human Mobility Research Centre, the Centre for Health Innovation connects researchers from across disciplines to tackle the most pressing human health challenges.

Cancer, infectious diseases, health data, and personalized care. The biggest challenges for human health can only be addressed by combining a range of expertise and disciplines. To foster these connections, Queen’s and Kingston Health Sciences Centre (KHSC) have partnered on the Centre for Health Innovation (CHI) – an initiative that brings together interdisciplinary investigators to fuel a solutions-based approach to translational health research, applying knowledge generated at the university to improving patient care and health outcomes.   

“CHI integrates insights from the frontlines of care to understand the real-world experiences and needs of patients and healthcare professionals,” says Amber Simpson, director of CHI and Canada Research Chair in Biomedical Computing and Informatics. “We are multidisciplinary because we understand the creative and innovative power of inclusion will forge a path to the next generation of transformative healthcare for all.” Members of the new centre have diverse backgrounds – from expertise in medicine, engineering, science, and technology to the humanities.

Amber Simpson presents at the Innovation for Good Symposium
Amber Simpson welcomes the audience to the first edition of the Innovation for Good Symposium, which celebrates the team work of the Centre for Health Innovation's members.

The Centre for Health Innovation is an evolution of Queen’s Human Mobility Research Centre (HMRC), which connected experts in medicine, engineering, and computer science to develop innovative treatments for bone and joint disorders. CHI will continue this work, while broadening its goals to address other health challenges, like infectious diseases, and using advanced technology to optimize treatment, diagnostics, and patient outcomes through precision medicine.

Solutions-based health research

The CHI team will pursue cost-effective, high-tech solutions that can be implemented within our current healthcare systems. This includes training and mentoring students and post-doctoral fellows in medical informatics, preparing Canada’s healthcare workforce to deal with rapidly growing field of digital health data.

A pivotal new connection spearheaded by CHI is building synergies between artificial intelligence (AI) and cancer research. Queen’s experts are looking at how machine learning techniques and artificial intelligence solutions might help physicians interpret cancer spread through imaging tests like CT scans and make better treatment decisions. While exploring new possibilities brought on by advancing technologies, the CHI team will also investigate the bioethical implications of using AI to predict metastasis and survival probabilities.

Also crucial for the future of the multidisciplinary centre will be the creation of shared facilities amongst the research community. In partnership with the Canadian Cancer Trials Group (CCTG), the Canada Foundation for Innovation, and Queen’s faculty partners including Health Sciences, Arts and Science, and Engineering, CHI will undertake a large-scale expansion of histopathology and biobanking resources at KHSC. This will expand KHSC’s capacity as the home of the CCTG biobanking facility and support research that will help investigators study the pathological basis of diseases.

Innovation for Good

Today and tomorrow (June 6 and 7), researchers are invited to virtually join the “Innovation for Good” symposium, that will kick off the new centre’s activities showcasing innovative, radically collaborative health research occurring across Queen's and KHSC. For more information, download the event’s program. Click here to register and watch the sessions.

CHI is also developing a state-of-the-art genomics facility to allow the complete analyses of the DNA and RNA molecules in an organism. This expansion leverages work throughout the pandemic on sequencing COVID-19 variants of concern for the province as well as long-standing expertise in cancer biomarkers. Through CHI, investigators will have the ability to leverage genomics and histopathology with data science, a winning combination to change patient outcomes.

While CHI’s objectives and mission are firmly planted on the ground, its research goals also aim for the stars. With proximity to clinicians and access to the human tissue bank, an interdisciplinary team is looking at the impacts of space travel on health, including bone loss and aging.

“We expect the shared resources and specialized facilities will allow innovation in precision medicine and digital health, in alignment with private sector interests, informing government policy, and attracting R&D investment”, notes Dr. Simpson. “Building on the work of HMRC, we are establishing an integrated, truly multi-disciplinary facility that we hope will become a province- and nation-wide resource to support health innovation and research. Exciting things are happening and Queen’s and KHSC are proud to be at the forefront.”

Got the sniffles? An expert’s tips on dealing with seasonal allergies

Increased temperatures and carbon dioxide concentrations caused by climate change and pollution can worsen symptoms.

Runny nose, sneezing, itchy/watery eyes, and occasionally coughing are the common symptoms of seasonal allergies.

Colourful flowers and delicate blossoms on trees are not the only sign that spring has truly arrived. For many, allergies are a sign the seasons have changed. Up to one in four Canadians suffer from allergic rhinitis and its symptoms – runny nose, sneezing, itchy/watery eyes, and occasionally coughing. With climate change, the problem might be getting more intense: experts believe increased greenhouse atmospheric concentration and higher temperatures cause plants to have longer flowering seasons, which leads to more pollen in the air. Also, seasonal allergies tend to be aggravated by air pollutants like diesel exhaust particles.

Anne Ellis, chair of Queen’s Division of Allergy and Immunology and clinical scientist at Kingston Health Sciences Centre (KHSC), is paying close attention to how seasonal allergies have changed in the past decade. She has some disconcerting news: it is still hard to distinguish patterns and make assertive predictions.

“Every year is different,” she says. “This year’s tree pollen season actually started on time compared to 10 years ago, but in more recent past we’ve had a very late start to tree pollen season, owing to much longer winters.”

Changing cycles

While 2021 saw record-breaking levels of birch pollen, so far 2022 has been more typical in terms of overall counts for Southern Ontario. In April, however, warmer days followed by cold nights and even snow brought pollination to a halt.

“Expect the unexpected when it comes to your allergies,” is Dr. Ellis’ main advice for those reaching for their antihistamines each spring.

But Dr. Ellis believes shortening spring and fall seasons – with longer winter and summer – make a big difference, at least in how people perceive their allergy symptoms.

“We wind up with a longer winter and more time to ‘forget’ how bad our seasonal allergies can be, so they affect us more dramatically when they come back,” she says.

North America is also seeing hotter summers with higher humidity, which can be a challenge for people with asthma. Because humidity fuels dust mite growth, even staying indoors doesn’t always provide relief – at least if one doesn’t have air conditioning or a dehumidifier.

Some practical tips

Dr. Ellis recommends that people suffering from seasonal allergies keep their windows closed and the air conditioning on when possible, and to avoid hanging clothes on clotheslines outside to prevent pollen capture. Rinsing the nose with a saline solution might help, too.

At local pharmacies, people can look for non-sedating, second generation antihistamines such as cetirizine or loratadine – Dr. Ellis says it’s better to avoid older, sedating antihistamines that might have unintended side effects and are not as effective as the new ones. If over the counter medicines are not enough to provide relief, she suggests seeing a doctor for prescription medications such as new antihistamines and intranasal corticosteroids, which reduce swelling and mucus in the nose.

In case these tips don’t do the trick, seeing a specialist might be the best option.

“Ask your doctor for a referral to an allergist to be skin tested and find out what you are allergic to specifically,” advises Dr. Ellis.  “An allergist can offer customized immunotherapy options based on these results that actually treat the underlying allergy, rather than just masking symptoms.”

From a public health perspective, Dr. Ellis says urban planning can make a difference, for example, in planting female trees that don’t pollinate – while they drop nuts and fruits, which can be messy, they don’t cause increases in pollen counts.

Research in action

Dr. Ellis leads the Kingston Environmental Exposure Unit at KHSC. In this facility, she and her team have a meticulously controlled environment that allows them to study the impact of allergens in health at any time of the year.

“The highly controlled indoor environment eliminates the variables of weather, participant environment, and the changing characteristics of seasonal allergens,” explains Dr. Ellis. “A proprietary computer-controlled delivery system and stringent monitoring ensure that the levels of allergen maintained in the unity remain within specific requirements.”

Since the 1980s, the unit has been used to advance our knowledge of how effective different anti-allergic treatments can be, including antihistamines, nasal corticosteroids and other medications.
